Question
Use the following probability model to answer the question.Event: For each adult resident in a city we ask how many vehicles they own.Number of Vehicles Probability0 0.041 0.412 0.383 0.134 0.035 0.01Find the probability that an adult resident has 3 or more vehicles. Give your answer as a number between 0 and 1.
Solution
To find the probability that an adult resident has 3 or more vehicles, you need to add the probabilities of owning 3, 4, and 5 vehicles.
From the probability model, the probability of owning 3 vehicles is 0.13, the probability of owning 4 vehicles is 0.03, and the probability of owning 5 vehicles is 0.01.
So, the probability that an adult resident owns 3 or more vehicles is 0.13 + 0.03 + 0.01 = 0.17.
